NSTB1002DXV5T1G

Overview

The NSTB1002DXV5T1G is a dual complementary biased resistor transistor (BRT) from onsemi, integrating PNP and NPN transistors with monolithic bias networks into a single SOT-553 package. The PNP section features a maximum collector-emitter voltage of -40 Vdc and a collector current of -200 mAdc. The NPN section supports a maximum collector-emitter voltage of 50 Vdc and a collector current of 100 mAdc. Thermal characteristics include a total device power dissipation of 500 mW at 25°C with two junctions heated and a junction-to-environment thermal resistance of 250 °C/W under the same conditions. The operating junction and storage temperature range spans from -55°C to +150°C.

Feature Summary

• Integrates a PNP and an NPN transistor with internal series base and base-emitter resistors to replace discrete components.
• Provides a compact SOT-553 surface-mount package suitable for space-constrained low-power applications.
• Simplifies circuit design by eliminating external biasing resistors and reducing overall component count.

Applications

• Low-power surface mount digital switching circuits
• Driver stages for logic interfaces requiring integrated biasing
• Space-efficient printed circuit board designs

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm pinout configuration and tape-and-reel specifications. Ensure the requested quantity matches standard packaging formats defined in the datasheet. Confirm RoHS compliance status and lead-free certification requirements prior to finalizing procurement orders.

Selection Notes

Select this component when both PNP and NPN switching functions are required within a single footprint. Verify that the application voltage does not exceed the respective -40 Vdc for the PNP or 50 Vdc for the NPN sections. Consider the SOT-553 package dimensions if board real estate is limited compared to larger transistor packages.

Part Context

This part belongs to the NSTB series of dual complementary BRTs from onsemi. It is designed to simplify biasing networks by combining two transistors and their associated resistors into one package. The SOT-553 form factor distinguishes it from single-transistor BRTs or those in larger packages like SOT-23.

Replacement Considerations

Direct substitutes must be dual complementary BRTs in SOT-553 packages with matching voltage ratings. Verify pin compatibility and internal resistor values before substitution. Generic single-transistor replacements will require additional external components.
